Transport properties of a reacting gas mixture with strong vibrational and chemical nonequilibrium Original Research Article

Transport properties of multi-component reacting gas mixtures are studied on the basis of the kinetic theory in the case of strong vibrational and chemical nonequilibrium. Considered are the conditions when quasi-stationary distributions of the molecules over vibrational levels do not exist and level kinetic approach is developed. The formulas for the viscosity, diffusion and thermal conductivity coefficients in terms of the nonequilibrium level populations, gas temperature and elastic collision integrals are derived. The practical algorithm for the calculation of these coefficients is given and applied for the investigation of the heat transfer behind a plane shock wave.
